Problems solved by technology

The fermentation conditions are uncontrollable, the process is very extensive, and a large amount of sewage and ammonia gas are produced, which affects the environment and personal safety
At the same time, too long fermentation time will easily lead to excessive decomposition of nutrients in the compost, which is not conducive to the production of straw mushroom mycelium and the increase of yield

Embodiment 1

[0031] (1) The formula of straw mushroom compost: 75 parts of waste cotton, 15 parts of bran, 5 parts of straw, 3 parts of biochar, 2 parts of potassium pyrophosphate (parts by weight). Straw length 2-3cm. Various raw materials are fully mixed and pre-wetted, and the water content is adjusted to 75%.

[0032] (2) Primary fermentation: Use a planer to plan the raw materials in (1), then enter the fermentation tunnel, and ferment (the stacking height in the fermentation tunnel is 1.5-2 meters, use a blower to ventilate, and the opening and closing time of the fan is 15-25 1 minute to open, 30-50 minutes to close. The culture material heats up by itself, and when the temperature of the material reaches 65 degrees Celsius, it can turn over and enter another tunnel.) One day; After the culture medium is fully stirred and mixed, enter another fermentation tunnel for fermentation (in the fermentation tunnel, the stacking height is 1.5-2 meters, and a blower is used for ventilation. ...

Embodiment 2

[0036] (1) The formula of straw mushroom compost: 75 parts of waste cotton, 15 parts of bran, 5 parts of straw, 3 parts of biochar, 2 parts of potassium pyrophosphate (both parts by weight). Straw length 2-3cm. Various raw materials are fully pre-wetted, and the water content is adjusted to 75%.

[0037] (2) Mixing and feeding: Fully mix the compost of (4) in Example 1 with the compost of (1) in this embodiment (the weight ratio of the two is 1:99), and directly lay the On the mobile cultivation bed frame, it is equivalent to 15kg of compost per square meter of dry weight.

[0038] (3) Circular secondary fermentation: move the mobile cultivation bed frame to the pasteurization room, feed a total of about 1200kg of steam, which is equivalent to 600kg of steam per ton of dry material, and adjust the ratio of the fresh air valve of the pasteurization room equipment to make the air The temperature rise rate is 5 degrees Celsius; when the air temperature reaches 60 degrees Celsiu...

Abstract

The invention relates to a fermentation method of straw mushroom culture material. The method comprises the following steps: (1) pre-wetting and mixing each component of the straw mushroom culture material, and adjusting the water content to 65-75%; (2) feeding: respectively taking a secondary fermentation culture material and the culture material in (1) with a weight ratio of (1-10):(90-100), conducting mixing evenly, and spreading the mixture on a mobile cultivation bed frame; (3) circulating secondary fermentation: moving the mobile cultivation bed frame to a pasteurization room for secondary fermentation. The fermentation method of straw mushroom culture material of the present invention can be extended backward in turn and recycled, which can save the one-time fermentation process ofthe straw mushroom culture material. The temperature rising speed of the culture material is fast, the steam consumption is greatly reduced, the fermentation time is shortened, and fast and efficientfermentation is realized.

Description

technical field [0001] The invention relates to the field of edible fungus cultivation, in particular to a fermentation method of straw mushroom compost. Background technique [0002] Straw mushroom (Volvariella volvacea) belongs to high-temperature, steady-temperature and firm grass saprophytic fungi. Its artificial cultivation compost generally needs to go through the process of primary fermentation and secondary fermentation. The first fermentation is carried out outdoors, and the compost is piled up, with a height of 0.7 to 1 meter and a width of 1.2 to 1.5 meters. The length is arranged according to the actual production volume; after several times of turning, it is put into the mushroom house for fermentation. The secondary fermentation can be heated by steam or fire. During the fermentation process, the air needs to be circulated and ventilated. When the temperature of each layer of compost reached 58-63°C, it was maintained for 8-10 hours, and the temperature was l...
